I have posted about this before, and I hope that's ok. I will continue to revisit this every few months until we figure it out. From what I have read this is a Hubitat problem and not a "me" problem, but I am happy to entertain any and all ideas.
I have multiple dashboards that I've built in Hubitat. I have 2 Samsung galaxy tab tablets wall mounted in my house. I also have 2 different iPhones using a dashboard. The Android tablets are utilizing fully kiosk browser and all power saving / hibernate / app suspend features are turned OFF. The iPhones are using Safari to load the dashboards.
Across all devices I get the same failure: the dashboards stop synchronizing after a few minutes to an hour if I'm lucky (it's random). The green check REMAINS GREEN - no red exclamation mark to say it isn't updating. In order to simplify this, I can also tell you that I have a simple clock running on the dashboards and even that clock stops updating the time. Finally, this dashboard has my security camera feeds running into it as images that get a mjpeg feed. The camera feeds ALWAYS REMAIN UP TO DATE on all devices. This is why I think this is a Hubitat issue. It proves that the devices are remaining connected to my network and are receiving data - the cameras stay live!
Any time that I do a manual page refresh, I get an updated dashboard, which as I said, remains updating for a few minutes to hours before it stops updating.
This is all running local, no cloud dashboards.
Can anyone give me any advice on how to diagnose and troubleshoot this? I would be happy to fix this for the community at large because I am certain this issue is not just me. I think dashboard updates are broken for the majority of users.
I can't claim any expertise that might shed some light on this, but if nothing else am curious about what the issue may be.
Do you have any "fancy" networking setup like VLANs or use of a Guest network for IoT devices, etc?
If we focus on the Samsung devices, have you tried ruling out Fully Kiosk and running the dashboards in a regular browser session (not sure if that is possible, haven't used Fully Kiosk myself)?
Have you tried opening the dashboards on a PC / Laptop to see if you experience the same behaviour?
I'll admit it is odd, and not something I have seen as consistently as what you are describing. So I expect there is something different in your setup, but cannot be sure what it is.
This happens to me too. Any local dashboard open for more than a few minutes stops responding. Get the little red exclamation.
Then of course, on remote dashboards, my hub variable tiles don't update when values change... I made a post about it and several people confirmed the issue, but there didn't seem to be any hint that anybody was looking into that issue either...
I have the same problem using Fully Kiosk. Fortunately, Fully Kiosk has an API and I can issue refresh commands to it and do it about every 2 minutes via Rule Machine. However I have found doing that causes an annoying memory leak in the Amazon Fire Tablet browser - which then needs to be rebooted once a week, but it works.
I do have VLANs and Guest / IoT networks, but the Hubitat, tablets, and our cell phones are all on the same internal network together. I use a UniFi Dream Machine.
I have tried a regular browser session (Chrome) and have the same behavior as with Fully Kiosk (which I believe is using the same Chromium engine under the hood).
Yes, on my laptop I get the same behavior opening the same dashboard on the same internal network. This is why I truly believe this is a Hubitat bug and would happy to be proven wrong!
I do have the API set to refresh every couple minutes, but it is very annoying if the refresh happens while we are using the tablet to do something such as arm / disarm HSM. Good advice though - thanks.
I have been troubleshooting this in my spare time for YEARS now. I have now determined that whenever I reset the ACCESS TOKEN the dashboard will properly update on my tablets for at least 24 hours before the problem resurfaces and updates stop. If I reset fully kiosk browser, reboot my tablet, delete all cache on it - NONE of this works. Only resetting the access token. I will say it for the millionth time - this is a hubitat bug that no one wants to investigate and fix. Help please?
Does anyone from the Hubitat team actually care about bugfixes and making your product actually work as advertised?
I now can tell you that the dashboard update issue is definitely a hubitat bug. Every night my hubitat reboots at 4AM and the dashboards stop updating. As soon as I create a new token, they update perfectly for the entire 24 hours --- does anyone want to troubleshoot and fix it? Hello? Crickets?
